Cryptfs: A Stackable Vnode Level Encryption File System

Erez Zadok, Ion Badulescu, and Alex ShenderComputer Science Department, Columbia University{ezk,ion,alex}@cs.columbia.eduCUCS-021-98Abstract: Data encryption has become an increasingly important factor in everydaywork. Users seek a method of securing their data with maximum comfort andminimum additional requirements on their part; they want a security systemthat protects any files used by any of their applications, without resortingto application-specific encryption methods. Performance is an importantfactor to users since encryption can be time consuming. Operating systemvendors want to provide this functionality but without incurring the largecosts of developing a new file system.This paper describes the design and implementation of Cryptfs -- a filesystem that was designed as a stackable Vnode layer loadable kernelmodule[5,15,19].Cryptfs operates by ``encapsulating'' a client file system with a layer ofencryption transparent to the user.Being kernel resident, Cryptfs performs better than user-level or NFS basedfile servers such as CFS[2] andTCFS[3]. It is 2 to 37 times faster onmicro-benchmarks such as read and write; this translates to 12-52%application speedup, as exemplified by a large build. Cryptfs offersstronger security by basing its keys on process session IDs as well as userIDs, and by the fact that kernel memory is harder to access. Working at andabove the vnode level, Cryptfs is more portable than a file system whichworks directly with native media such as disks and networks. Cryptfs canoperate on top of any other native file system such asUFS/FFS[8] andNFS[11,16]. Finally, Cryptfs requiresno changes to client file systems or remote servers. 1.
